Terminology registries (TRs) are a crucial element of the infrastructure required for resource discovery services, digital libraries, Linked Data, and semantic interoperability generally. They can make the content of knowledge organization systems (KOS) available both for human and machine access. The paper describes the attributes and functionality for a TR, based on a review of published literature, existing TRs, and a survey of experts. A domain model based on user tasks is constructed and a set of core metadata elements for use in TRs is proposed. Ideally, the TR should allow searching as well as browsing for a KOS, matching a user's search while also providing information about existing terminology services, accessible to both humans and machines. The issues surrounding metadata for KOS are also discussed, together with the rationale for different aspects and the importance of a core set of KOS metadata for future machine-based access; a possible core set of metadata elements is proposed. This is dealt with in terms of practical experience and in relation to the Dublin Core Application Profile.
Metadata Elements for Object Description and Representation: A Case Report from a Digitized Historical Fashion Collection Project10/06/1999
This project’s goal is to develop a catalog for a digitized collection of historical fashion objects held at the Kent State University Museum and to analyze and evaluate how well existing metadata formats can be applied to a fashion collection. The project considered the known and anticipated uses of the collection and the identification of the metadata elements that would be needed to support these uses. From a set of 90 museum accession records, 42 fashion objects were selected for cataloging. Three metadata treatments were created for these 42 items using (a) the Anglo-American Cataloguing Rules (AACR) in use with the United States MAchineReadable Cataloging (USMARC) formats, (b) the Dublin Core set of elements designed for minimal level cataloging, and (c) the Visual Resources Association (VRA) Core Categories for Visual Resources created for developing local databases and cataloging records for visual resources collections. Comparison and analysis of the formats resulted in the adoption of a modified VRA metadata format to catalog the entire digitized historical fashion collection.
